Description The LT8641SXE is a Transition Minimized Differential

Signaling (TMDS) switch that enables the connection of

multiple High-Definition Multimedia Interface (HDMI) source

devices to high-definition television (HDTV). Based on the

HDMI 1.4 specification, LT8641SXE is an advanced TMDS

switch that delivers a cost-effective method for manufacturers

to add additional HDMI ports to their HDTV. Multiple HDMI

ports allow consumers to connect variety HDMI-enabled

sources to their HDTV. It supports HDCP 1.4 specifications,

and Audio Return Channel function.

The LT8641SXE is a four-to-one (4:1) switch ideally suited for

use in the back panel of HDTV and A/V receivers, allowing

consumers to connect multiple HDMI-enabled devices such

as high-definition DVD players, set top boxes and game

consoles. The LT8641SXE switch selects a single HDMI or

Digital Visual Interface (DVI) signal from the four receiver ports

and generates HDMI/DVI audio/video output, as well as

DDC/HPD switching, in full compliance with the HDMI and DVI

specifications. The LT8641SXE also acts as a HDMI receiver.

It extracts the digital audio information from the HDMI packet,

and recovers digital audio to I2S/SPDIF interface. So it can be

applied to the multi-channel audio amplifier for best audio

effect. This feature can enable an external HDMI switching

box acts as a home entertainment box that can output up to

8-channel high quality audio signal for the best audio effect.
